Abstract
A cylindrical lithium ion chargeable cell is provided, which comprises a cell casing, in which an electrolyte bag and a cell-protecting circuit board connected with the electrolyte bag are provided. The cell-protecting circuit board is electrically connected with the positive and negative pole. The cell casing is of traditional cylindrical shape, and the positive pole is at upper, the negative pole is at lower. At implementation, the cell casing is taken as a main body, the arrangement sequence of parts from up to down is a positive pole cap, the electrolyte bag, the cell-protecting circuit board, and a negative pole board. With the rapid development in miniaturization of electronic devices, the utility model realizes miniaturization and profiling of the cell-protecting circuit board for the lithium cell, allows the shape of the lithium cell to be consistent with the using habit of people. The special feature of a round body enables a lithium cell of same volume to have higher capacity.
Description
Technical field
The utility model relates to a kind of lithium ion battery of repeatedly recharge, refers in particular to a kind of and general dry battery and the consistent column lithium ion rechargeable battery of common rechargeable battery moulding.
Background technology
Along with the fast development of electronic apparatus, be suitable for the miniaturization of young colony and outdoor activity colony, the important branch that portable electronics becomes development day by day especially, thereby also more and more higher to the demand and the requirement of power supply.Because electrical equipment autogamy rechargable power supplies heaviness, so how to solve power issue with compact battery.Battery has developed, has occurred more to save and the hydrogen base rechargeable battery of environmental protection also on traditional manganese backbone battery basis, and then has occurred again that capacity is bigger, the Li-Ion rechargeable battery of memoryless restriction (hereinafter to be referred as lithium ion battery).Because the advantage of all many-sides such as capacity and discharge time, the lithium battery that adopts mostly is lithium ion/lithium polymer battery now, and along with the development of lithium-ion electric pool technology, its cost performance improves constantly, and causes it by all trades and professions extensive use.Existing commercially available dry cell and hydrogen base rechargeable battery be free space maximum cylindrical to take the volume minimum mostly, the basic structure moulding is the battery barrel of interior dress chemical substance, cylindrical shell upper end be provided with positive electrode cap and loam cake, the tube end for or be provided with the negative pole contact jaw, drum surface is ornamental packing.Why not used for lithium ion battery always this Mechanical Builds of being used widely is; basic reason is to contain the explosive characteristic of lithium ion material; lithium ion battery must be furnished with and prevents to overcharge the protective circuit plate that causes overtension, and the electronic component of circuit board and carrying thereof has produced greatly restriction to the moulding of lithium ion battery.
The utility model content
The problem of the required solution of the utility model provides a kind of approach of column lithium ion rechargeable battery various shapesization, makes the moulding of lithium ion battery meet people's use habit.
Designed a kind of column lithium ion rechargeable battery according to the above-mentioned problem that needs to solve; comprise battery container; the battery protection circuit that in housing, is provided with electrolyte bag or electric core and electrically connects with it; battery protection circuit connects with anodal and negative electricity; being shaped to of battery container is traditional cylindrical, and is anodally descending at last, negative pole.During enforcement, based on battery container, putting in order of each parts is followed successively by positive electrode cap, electrolyte bag or electric core, battery protection circuit, negative plate from top to bottom.
The utility model has benefited from the fast development of electronics miniaturization; miniaturization, the heteromorphosis of lithium battery protection circuit plate are achieved; the moulding of lithium battery is consistent with people's use habit thus, and has bigger capacity because of the distinctive characteristic of round makes the lithium battery of equal volume.
Description of drawings
Accompanying drawing 1 is a parts decomposing schematic representation of the present utility model; Accompanying drawing 2 is connecting relation schematic diagrames between positive pole and battery protection circuit in the accompanying drawing 1; Accompanying drawing 3 is the schematic perspective views after the utility model assembling encapsulation.
Embodiment
With reference to accompanying drawing.Now the assembly structure of the utility model lithium battery is sketched in after, cylindrical battery housing 2 external fixation be equipped with decorate packing material 1, in electrolyte bag or electric core 3 are housed, the immediate shipment timing is object of reference with the housing.Assemble sequence in housing is; be followed successively by positive electrode cap 4, electrolyte bag or electric core, battery protection circuit 6 from top to bottom, with the negative plate 8 of electrolyte bag or electric core and battery protection circuit UNICOM, the battery circuit baffle also can be arranged between anodal and electrolyte bag or the electric core certainly.Wherein, positive electrode cap connects by sheet metal 5 with the battery circuit baffle; negative plate 9 be external negative pole end with the battery circuit baffle between realize connecting and be close to the support of battery circuit baffle by sheet metal at 7 the end; support 7 mainly positions and fixes the battery circuit baffle; this support is positioned at below the electric core, and battery protection circuit is fixed on below the support or wherein and be positioned on the negative plate.
So far as seen, the utility model moulding not only meets traditional habit but also satisfied the needs that are issued to the capacity maximum with volume; Production process meets traditional lithium ion battery production process technology fully, existing procedure technology be need not to transform, and encapsulate simple and conveniently, can effectively enhance productivity.
Claims (5)
